That little "swishy-swishy"heartbeat is the BEST sound in the world.
I'm 22 weeks pregnant now, and I live for it. Along with my five year old daughter saying, "wake up mommy, God's brought another day."
Too cute. When my daughter was around 3, she'd say, "Sun's awake. Time to play!"
God bless you and your family! My prayers for a safe and healthy delivery, a quick recovery, and a baby that doesn't have his/her days and nights mixed up for the first 6 months :)
